TURF EDGER Filed March 19, 1932 m n w n 3 Patented July 4, 1933 JOSEPH F. nmrnenai on TOLEDO, oHIo TURF nnenn Application filed March 19, 1932. Serial No. 599,885.

' My invention has for its object to provide a turf edger tool having means for readily the tool to vary the" depth of the; edging groove formed by the tool in the turf.

adjusting The invention has for its particular object to provide a turf edger tool Winch has means for deflecting and directing the turf removed by the cutting portion of the toolfrom the groove and to the edge oi the groove from 'where'it can be easily collected and removed.

Another object of the inventionis to provide a turl edging tool having means for moving the tooleasily over the turf whereby the turf ed iig may be quickly performed with a m i nuin outlay of force applied to the tool. Another object of the invention is toprov ide, anefiicient turf edging tool of low cost. I

The invention consists'in other'features and advantages which will appear from the'following description an d'upon examination of the drawing". Structures containing the invention niay partal ze' of difierent forms and maybe varied 1 their details and Stlll embody theinvention, To illustrate a practical application of the nvention I have selected a turf edging toolembody ing the invention as an exampleof the various structures and details thereof that contain the invention and shall describe the selected structure hereinafter, it being understood that variations may be made without departing from the spirit of the invention. The particular structure selected is shown in the accompanying drawing. I

Fig. 1 of the accompanying drawing illustrates a perspective view of the turf edging tool chosen for purposes of illustration. Fig. 2 illustrates a side view of the turf edger.

Various tools have been heretofore used for the edging ofturf. Theobjection to many these tools resides in the amount of labor that must necessarily be expended inorder to operate the tool and in the un-uniform results that are obtained, The tool provided by my invention has a scoop which is con- 5 nected to a handle and is supported on a wheel or roller which may be adjusted with reference to the scoop so as to vary the depth of the groove desired in edging the turf. The wheel or roller is adapted to roll on the Walk and prevents the scoop from varying itsdig ging action. thus digging a groove of uniform depth throu hout. Thusythe scoop may be lowered to below the turf line where, as is frequently the case, the level of the walk is substantially higher than the levelof the turf tobe edged. The scoop provided with a bowl the walls'of which cooperate to'deflectand direct the loosened turf to a posi-- tion of discharge along side of the groove from where it'may be easily collected and re moved. The scoop also provided with a share which has ri'u'ved cutting edges and servesto deflect the scoop aboutobstructionsfl with which the scoop may meet in perform jug tne turf edging operation. The partieular'turi edger selected for-pur- "poses of illustration hasa scoop 1 which is connected by'a pair-of brackets 2 and bolts 3 to the handle a The scoop may be moved downwardly into the ground'by exerting a pressure on the handle 4 thus locating the oop in position for immediate operation. In order to guide and support thescoop 1 as it moved through the turf 6, a Wheel 7 is connected to the scoop by'a suitable axle member and mu; 8. The axle member 8 extends through slots'lO formed in each of the brackets 2. In order to provide for adjustability of the scoop relative to the wheel 7 and therefore to enable the operator to vary the depth into the turf 6 at which the scoop lf moves, the'slots 10 are provided with connecting slots or recesses 12 which extend. from the slots 10. The slots 12 are located at an. angle to the line of the slots 10 andparallel to the line of the handle 1.

The axle member may thus be located in any of the recesses 12 according to the adjust ment desired'and will be increasii'igly held in position in the slots 12 as the force applied to the handle to move the scoop increases.

. The scoop is provided with a prow or share 14 Which'has curving sharpened edges 15 and 16 Which meet to form an extending point 17 at the lower portion of the scoop. As the edging of turf is commonly performed immediately adjacent to Walks, such as the walk 18, which are formed of cement or the like, the scoop is forced along the edge'of the walk 18, being supported by the wheel 7 to form a groove 22. The point 17 of the share 14 cooperates with the edge 15 to guide the share and scoop about any adjutting or irremovable obstacles, such as portions of concrete which commonly extend from the bed of the walks.

As the turf is cutby the proW' 1 1 the loosened turf 21 is directed rearwardly towards the bowl of the-scoop 1. Ihe bowl 20 has walls which curve upwardly and toward one side of the scoop so as to direct the loosened turf 21 upwardly and to one side of the groove 22, where it is discharged. Preferably, the walls of the bowl 20 are curved so as to direct the loosened turf toward the surface of the walk 18 from whence it can be easily gathered and removed.

In order to prevent the loosened turf 21 from escaping over the top of the bowl 20 and falling back into the groove 22, a top plate 25 is provided over the bowl 20 and of curved plates attached to the handle in parallel opposite relation to one another, each of the said pair of plates having correspond ing longitudinal slots and a plurality of laterally extending slots leading therefrom, a shaft extending through a selected pair of lateral slots for slidable support therein, a

Wheel rotatably mounted on one end of the shaft, an L-shaped cutter member secured to one of the parallel plates comprising a vertical blade having a vertical concave undercutting knife edge and a basal horizon; tal blade having a concave cutting edge receding from the point of juncture with the vertical undercutting edge, an upwardly concave deflector extending from the cutting edges ofthe L-shaped cutter member and extending vertically to the top of the vertical leg thereof,-and a horizontal plate joining the vertical leg of the L-shaped cutter member and the deflector whereby sod cut by the advancing blades is deflected in a direction perpendicular to the face of the vertical leg and asidefrom the path of the cutting edges. y

2. In a turf edging tool, a handle, a pair of curved plates attached in parallel positions to opposite sides of one end of the handle and forming curved extensions to thehandle, a pair of corresponding. longitudinal slots having a plurality of lateral branching slots formed in each of the said pair of plates, a shaft extending through a selected pair of lateral slots for adjustable support therein, a wheel attached to one end of the shaft, a cutting bladeattached to one of the curved extensions of the handle, one edge of the cutting blade having a concave under cutting knife edge formed thereon and another edge having a second concave cutting knife edge extending from the end of the first cutting edge to form a receding prow at the point of juncture of the edges, an ellipsoidal upwardly directed deflector extending from the cutting edges, and a plate extending perpendicular to the parallel slotted plates and joining the de flector and the edge of'thecutting blade.

In witness whereof I have hereunto signed I my name to this specification.
